Hold'em table

7-6 suited has reasonable playability on the button, and a small opening raise can pressure the blinds while retaining maneuverability.

A7o is a solid hand to 3-bet from the SB against a button open in a 3-handed pot, applying pressure and building the pot while having position advantage post-flop is less relevant but fold equity against BB is valuable.

A8o is a marginal hand in early position facing a significant reraise to 800. With two opponents already invested and the effective stack dynamics unfavorable, folding preserves chips for better spots.

76 offsuit is too weak to continue against a substantial 3-bet out of position with the big blind folded.

J4 offsuit is a weak hand from the button facing a raise; folding preserves chips for better spots.

Jack-four offsuit is a weak hand with poor win equity against a big blind. Folding the small blind here minimizes losses on a marginal holding.

8-6 offsuit is a weak holding from the button. With a small blind and big blind already in, folding preserves chips for stronger starting hands, which is the correct long-term strategy.

9-5 offsuit is a weak blind-versus-blind holding and does not warrant completing out of position.

Raise the button with suited KQ for value and initiative in a three-handed pot.

K2 offsuit is weak; facing a raise with two players left to act behind, folding is the standard discipline.

Q5o is a weak hand with poor equity against a raise from the button. With 200 chips to call and only 9900 remaining, folding preserves chips for stronger opportunities. The raiser has position and likely has a stronger range.

Pocket pair on the button; raise to build pot and take initiative, small pair can call small bets or fold to resistance.

6-10 offsuit is a weak hand with poor equity against a 3x raise from the button. Folding preserves chips for stronger opportunities.

QTs is a strong suited broadway hand versus a button open and performs well as a value-oriented 3-bet. Raising also denies equity and takes initiative heads-up.

Pocket threes have good implied odds to call a 3-bet with deep stacks behind, set-mining rather than folding or re-raising.

Betting small for value and protection with top pair in a heads-up 3-bet pot, while keeping weaker queens, pocket pairs, and draws in.

Flopped bottom set, a very strong hand on a dry board; raising for value while stacks are still deep enough to build the pot.

Top pair with a reasonable kicker is too strong to fold to this flop raise in a heads-up 3-bet pot. Calling keeps bluffs and heart draws in while avoiding inflating the pot against stronger queens or sets.

Top pair has solid showdown value but is not strong enough to build a large pot after the opponent's substantial flop raise. Checking keeps their bluffs and draws in while controlling the pot.

My pocket 3s have no real equity on this Q-9-4-2 board, so with opponent checking I should take a free card rather than bluff further into a hand that likely has a pair.

Top pair with a decent kicker is worth a thin value bet after the turn checks through. A smaller sizing can be called by weaker queens and some bluff-catchers while limiting exposure to a river raise.

Pocket 3s have no pair on this board and little bluff-catching equity; the check-check-then-river-bet line looks like a trapped strong hand, so folding is the +EV play.

4-2 offsuit is one of the weakest hands in poker. Folding from the button preserves chips and avoids a difficult postflop situation with a dominated hand.

7-3 offsuit is too weak to continue from the small blind against the big blind.
